scale and in side elevation of the outerend Be it known that I, FRANCISLEE STUAnT,,, of the apparatus. I

a citizenof the United States, residing at New York city, in the countyand State of New York, have invented certain new and useful Improvementsin Apparatus for Conveying, Delivering, and Gathering Material, of whichthe following is a specification.

This invention relates to apparatus for carrying material brought from adistance by a main conveyer belt to a pile or place for storage ordelivery, and also to apparatus for gathering material and depositing iton a conveyer belt which carries it to a distant point. Apparatus ofthis general kind is shown in my United States Patent No. 1,325,812 ofDecember 23, 1919. In that patent I have shown a trip-per associatedwith a main conveyer belt which delivers to a boom conveyer which inturn discharges the material from its outerend and piles or stacks it.The boom conveyer carries a grab bucket equipped with suitable operatingdevices, by means of which the material may be gathered and deposited onthe main conveyor belt and conveyed to a distant point or dischargedwherever desired.

According to my present invention I provide a combined stacker andgatherer in which the grab bucket instead of being supported by the boomconveyer is hung from the outer end of the boom of a crane, and the boomconveyer is mounted to extend through the crane boom and is supportedthereby at a considerable distance from its pivoted inner end. The boomconveyer is equipped with rollers which operate in guides in the craneboom so that while the outer portion of the stacker boom is supported bythe crane boom, the former may be raised and lowered'by the crane boomwhen the latter is moved vertically and a pivotal connection is providedbetween the stacker boom and the crane boom which permits of therelative movements of the two booms while they are being moved. In thisway I provide a combined stacker and crane of simple but efiicientconstruction and which may be easily operated.

In the accompanying drawings Figure l is a side elevation of a combinedstacker and gatherer embodying my improvements.

Fig. 2 is a detail view on an enlarged Fig. 3 is a plan view of theapparatus shown in Fig. 1.

Fig. 4 is a plan view on an enlarged scale oi the lower part of theapparatus, with crane boom and stacker omitted.

Fig. 5 is a view on an enlarged scale and in side elevation ofpartsofthe mechanism.

A main conveyer belt A, which may be 01"- any desired length to conveymaterial from a distant source of supply, is provided with a loopedportion or tripper A supported by a frame 13 mounted on a truck C, thewheels 0 of which traverse a track D running parallel with the mainconveyer belt. The belt A passes over a deliv ery roller a at thetop ofthe frame B and thence passes to drive pulleys E and F to which power'isapplied by a motor G. Thence the belt passes over a tension pulley H andthen forward as indicated. The pulley H is carried by a suitable frameto which is connected a rope J extending over a pulley j and thence overapulley 7c and carries a counterweight K. By this mechanism the desiredtension is given to the tripper and main conveyer belt. The mechanismjust described'is substantially the same as that shown in my UnitedStates Patent No. 1,317,997 of October 7, 1919.,

The tripper delivers through a hopper L to the inner end of a conveyerbelt m on the stacker boom M. The belt m is driven by motor mechanism Nand the stacker boom is pivoted at a to a frame O carried by a turntableP which is mounted on a truck Q, the wheels q of which trav erse thetrack D. The truck Q is connected with the wheel supported frame B whichby a turntable, the material may be deliv-r ered in any desired verticalplane.

The crane boom R is pivoted at its lower end to the turntable P at andis free to turn about a horizontal axis so that its outer anism t on thetruck.

raised and lowered'by a rope U connected bucket of well knownconstruction, which is operated by a rope T connected with a Windlass toperated by suitable motor mech- The crane boom 1s at u with the outerend of the crane boom andextended to a motor operated Windlass V on theturntable P. The motors V are geared as shown at o to a shaft 0, whichis geared at o to mechanism for rotating the turntable The crane boomisot skeleton construction and has a longitudinal opening in it throughwhich the stacker boom extends. The outer portion of the stacker boom isequipped with rollers m which travverse guides 09 on the crane boom, thear rangement being such that as the crane boom is raised and lowered thestacker boom is also correspondingly moved and is at all times supportedand braced near its outer end or at a considerable distance from itspivotal connection with the truck.

; By the mechanism shown the crane boom may be set at any desired anglerelatively to "the ground level and will correspondingly raise and lowerthe stacker boom which may thus be set to deliver from any desiredhorizontal level or at any desired distance from the ground. Inasmuch asthe crane boom =18 supported by the turntable and as the stacker boom isconnected with the crane boom to move with it sidewise or about avertical axis, the crane boom may be set to deliver material at anydesired vertical plane; It will be observed that when the turntable ismoved about its axis it not only moves the stacker boom sidewise byreason ofthe connection between the inner end of the stacker boom andthe frame of the turntable, but a sidewise movement is imparted to theouter portion of the stacker boom by reason'of its connection withthecrane boom.

An. important feature of the invention consists in pivotally connectingthe inner end of a stacker boom to a turntable and in supporting theouter portion of the stacker boom by another boomwhich is connected tothe turntable below the pivotal connection of the stacker boom with theturntable. Such construction'is simple and eflicient and provides novelmeans for supporting and bracing the outer portion of the stacker boom,which in somecases is of great length. This feature of my invention isbelieved to be novel whether or not said supporting boom "is used tosupport gathering mechanism.

which may discharge onto the main conveyer belt as described in myPatent No. 1,325,812 of December 23, 1919, above mentioned.

I claim as my invention p 1. An apparatus for delivering material,comprising a truck, a turntable thereon, a vertical frame on theturntable, a stacker boom equipped with a conveyor and pivotallyconnected at its inner end with the frame on the turntable to move aboutthe horizontal axis, a main conveyer belt delivering to the stackerboom, and a boom connected with the outer portion of the stacker boom ata considerable distance from its pivotal connection with the turntableand which is pivotally connected with the turntable below the inner endo1 the stacker boom.

2. A combined stacker and gatherer, com prising a'truck, a turntablethereon, a crane boom pivotally connected withthe turntable to moveabout a horizontal axis, gathering mechanism carried by the crane boom,

means on the turntable foroperating said gathering mechanism, means onthe turntable for raising and lowering the crane boom, a main conveyerbelt equipped with a tripper, a stacker boom provided with a belt towhich the tripper delivers, a pivotal connection between the stackerboom and the turntable permitting the stacker boom to move about ahorizontal axis, and sliding connections between the outer portion ofthe stacker boom and the crane boom whereby the outer portion or" thestacker boom is supported by the crane boom and the stacker boom israised and lowered by said crane boom.
